The Sapalli Culture is the Southern Uzbek variant of the Late Bronze Age Namazga VI complex. It is a culture of sedentary farmers
settling along the tributaries of the Surkhandarya river. In the archaeological literature this region is also referred to as Northern Bactria.
Presently five sites are known, which have been studied since the 1960s. The eponymous site of Sapallitepe and Dzarkutan were
explored by the Archaeological Institute of the Uzbek Academy of Science under the direction of A. Askarov. At the latter site, the
German Archaeological Institute was active between 1994 and 2003. The Institute of Art Historical Research worked at Mollalitepe.
A large necropolis in Bustan is currently being dug by N. Avanesova (University of Samarkand). Tilla Bulak is the most recently
discovered Sapalli Culture site. Besides, surface finds were made near Denau and in the Zerafshan Valley. In its material culture close
relations exist with both Western Tajikistan (Tandyrjul) and Northern Afghanistan (the oasis of Dashly).
